Genetically Modified Organisms (GMOs)
An organism whose genetic make-up has been somehow modified by humans for our benefit.
Bt plants: insecticide, golden rice, flavr savr tomato

More GMOs
Cows engineered to produce HGH (Human Growth Hormone)
Nitrogen producing plants-decreased need for fertilizer

Controversy
Is it safe?Antibiotic resistanceNatural
populations/ecosystemGenetic modification of
animals & humans

Spiders + goats…
Canadian scientists combined spider DNA with the cells of lactating goats, they produced silk with their milk
That’s weird right?

Gene Therapy
Introducing a healthy gene to replace a diseased gene in a human being.
Viral vector

Jesse Gelsinger
Volunteered for experimental gene therapy in 1999
18 yrs old
Died a few days after from massive reaction to viruses

How is it done?

What is wrong and what is right?
Ethics, where do we draw the line? Do we draw the line?
Is it safe?GMOs disrupting the balance of nature? I Am Legend Zombies?
